You should be able to access all of your ebooks and courseware by selecting the title from your “My Course Materials” page in Canvas and clicking the “Read Now” button.
If nothing happens when you click "Read Now", you may want to make sure you have any pop-up blocker add-ons or extensions disabled as those can interfere with digital material launching.
Some users trying to access Canvas via Safari may find that their browser itself automatically prevents books from launching when they click "Read Now". If you're using Safari, you'll just need to allow pop-ups to let the book open.
If you are still having issues accessing your digital materials after these steps, please contact RedShelf so they can investigate further.
